Q

● the simplest level of protein structure
● is simply the sequence of amino acids
in a polypeptide chain.
● is attached together by a covalent pr
peptide bonds.
● this process is done during the
biosynthesis or translation

A

Primary Structure

17
Q

the most common types
of secondary structures
are the α

A

helix and the β
pleated sheet.

18
Q

Is the overall three-dimensional
structure of a polypeptide
● Is primarily due to interactions between
the R groups of the amino acids that
make up the protein.

A

Tertiary structure

19
Q

The quaternary structure of a protein is the
association of several protein chains or
subunits into a closely packed
arrangement.
● Each of the subunits has its own primary,
secondary, and tertiary structure

A

Quarterly structure

20
Q

Protein serve us;

A

● Structural support
● Biochemical catalysts
● Hormones
● Enzymes
● Building blocks
● Initiators of cellular death

21
Q

● Known as immunoglobulins
(lg), these are Y-shaped
proteins that help in
protecting the body by
fighting all foreign bodies
called antigens.
● Example:
Immunoglobulin G (IgG)

A

Anti body

22
Q

are proteins that
transmit signals to coordinate biological
processes between different cells,
tissues, and organs.
Example: Growth hormone

A

Messenger Protein

23
Q

● These are a type of protein that
provides structure and support for cells.
● Example: Actin, Myosin

A

Structural Components

24
Q

● These are proteins that bind and carry
molecules within the cells and
throughout the body
● Example: Ferritin

A

Transport Storage

25
Q

The process of making protein from RNA.

A

Protein Synthesis

26
Q

There are two steps of protein Synthesis;

A

○ Transcription where DNA is copied to
RNA
○ Translation where ribosomes read the
RNA to make proteins.
